Chemistry - Chemical elements or compounds with yellowish white color
Solution 1:
- Aluminium(III) chloride - often described as white but samples is sometimes contaminated with iron(III) chloride giving it a light yellow color
- Antimony(V) oxide - pale yellow solid
- Bismuth(III) oxide - light yellow solid
- Rhodium(III) oxide - lemon yellow
- Cerium(IV) oxide - pale yellow-white compound
- Dysprosium(III) nitrate - white to pale yellow
- Holmium(III) oxide- Color depends on lighting condition. In daylight, it is tannish light yellow; Under trichromatic light, it is fiery orange red (Thanks @EdV)
- Samarium(III) oxide - light yellow
- Silver(I) iodide - samples can have a range of color(white to pale yellow to yellow) due to impurity and photosensitization
- Selenium(IV) chloride - white to faint yellow volatile solid
- Gold(III) chloride - pale yellow to yellow
- Potassium Telluride - pale yellow
- Thallium(III) bromide - pale yellow
- Some vanadate salts are light yellow
Bromium nitrate is pale yellow but not confirmed. Silver(I) bromide and lead(II) bromide are light yellow and white cream colored respectively.

Solution 2:
Calcium hypochlorite is an example of such a yellowish white compound.
Another example would be Silver Bromide
Solution 3:
The reaction of any acid on a thiosulfate solution makes a precipitate of sulfur $\ce{S_8}$ which is pale yellow, nearly white.
Solution 4:
Undyed ("natural") nylon is yellowish-white:
